I really feel bad about derailing Jedi Loreen's thread, so I won't be posting there anymore. If you have any questions about LED blades, post them here and I'll try to answer. While there are people considerably more experienced than me (Corbin, Shannon, Ionsabers, etc), I have built several LED and EL sabers, and have converted some MRFX LED sabers to Luxeon and will answer whatever I can. If there is anyone else out there with LED expertise, I'd love to swap some info with ya. Here's some general info. The LED's being used in most of the LED sabers being created now days are 1watt and 3watt Luxeons. The 1watt Luxeons come in Star/o form, which includes the LED emitter, optics, and an aluminum plate: [image=http://www.lumileds.com/images/productphotos/white_star_o.jpg] Star/o's are easy to work with and produce very little heat. Different colors have different brightnesses on the Star/o's. The brightest colors are red, red/orange, and green which are rated for over 50 lumens. You can see the different colors and their lumen rating on the manufacturer's website, you can order the LED's from there as well: http://www.lumileds.com/products/family.cfm?familyId=2 The power setup I have been using for 1watt Luxeons has proven to be easy and reliable: Four AAA batteries run in series through an 8ohm 1watt resistor directly to the LED I use AAA's instead of AA's because I use a smaller 1.25"OD hilt instead of the larger 1.5" As for the blade, I use 1" polycarb with the 1/16"OD from USplastics. It's inexpensive, and has proven to be very rigid with hardly any flex. For the diffuser, I have been using the custom blade film from Corbin Das http://www.youcanknow.org/corbin The Star/o fits inside the blade up to the aluminum plate. The technique I use is to secure the Star/o under the blade holder inside the hilt. Then the blade slides inside the blade holder, over the star/o, and is held in place with a thumb screw. There is nothing inside the detachable blades of my sabers except the blade film. The hilt contains the LED inside and if you're walking around outside without the blade, the hilt makes a nice torch. It's nice not having to worry about frying an inverter by accidently hitting the power with no load. Anyway, if you can think of anymore questions, post em.
